Application [ilcd May 1G, 1887. Serial No. 238,349. (No model.)

To @ZZ whom, t may concern:

Be it known that I, CHARLES H. SHULTZ, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and useful Improvement in Vapor-Burners, of which the 'following is a specification.

My invention relates to an improvement in vapor-burners; and it consists in the peculiar construction and combination of devices, as will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is a vertical central sectional view of a vapor-burner embodying my improvements. Fig. 2 is a top plan View of the same.

Arepresents a hollow annular casting, which surrounds a vertical central opening, B, or space,that is entirely openfrorn top to bottom. From one side of the casting A projects an offset, C, which comprises a cap for the usual stand-pipe, D, and is provided with screwthreads to engage similar threads on the upper ends of the pipe, thus enabling the latter to be secured firmly to the casting A. The said casting constitutes the generating-chamber and receives its supply oi" oil from the stand-pipe D in the usual manner. From the opposite side of the generating-chamber extends a vaporpipc, E, to the lower end of which is attached a horizontal sleeve, F. G represents a needlevalve which works in the said sleeve and is adapted to open or close the aperture H at the inner end of the latter:

From the inner side ofthe cap C projects a horizontal ear, l. K represents an arm which depends from the generating-chamber on the side opposite the ear I, and the lower end of the said arm is bent outward at right angles to forni an ear, L.

M represents a combined mixing-chamber and burner-head, having a removable cap, N, on 'its upper sidc,pro\-ided with vertical openings O. The central portion of the said cap is depressed to form an oil-cup, P. From opposite sides of the combined mixing-chamber and burner-head project horizontal ears R and R'. The ear R bears against the under side of the ear L and is secured thereto by a bolt or key, S. The ear R bears upon the upper side of the ear I and is secured thereto by a bolt or key, S.

T represents a vertical bolt, which extendsl downward through a central opening in the cap N and also through an opening in thc lower side ofthe mixing-chamber and burnerhcad,and is provided with a clamping-nut, T. This bolt serves to secure the cap rigidly iu place on the upper side of the mixing-chamber and burner-head. Formed with and projecting from one side of the combined mixingcharnber and burner-head is a tube, U, the outer end of which is open, and is arranged on the same horizontal plane with and is presented toward the inner end oi' the sleeve F.

By reference to Fig. 1 it will be seen that the mixing-chamber and burner-head is arranged directly below the generating-chamber Land thereby the jets of flame from the openings O in the upper side of the burner-head are caused to strike directly against the under side of the generating-chamber, so as to heat the same so intensely as to instantly vaporize the oil which is fed thereto.

It will be further noted that the exterior atmosphere communicates with the space between the bottom of the generating-chamber and the top of the burner, and thus insures a sufficient quantity of air to be constantly fed to the flames as they pass upward through the opening B to cause complete and perfect combustion of the vapor.

The operation of my invention will be very readily understood. A small quantity of oil, previously placed in the cup N, is lirst ignited to heat the burner and the chamber A, and a supply of oil is fed to the chamber A. by the stand-pipe. As the oil reaches the chamber it is vaporized by the heat, and is fed through the pipe E and the sleeve `F and directed upward from the latter through the tube M into the burner. As the vapor passes through the tube air is sucked in with it and becomes coinmingled with the vapor in the burner, thereby rendering the same combustible by oxygenizing it. As the oxygenized vapor escapes through the opening O it is burned, as previously described. Y

Particular stress is laid on the construction of the cap N with the depressed top forming the oil-cup; also the location of the burner and commingling-charnber below the generator A, with the openings O directly on a line with the bottom of the chamber A, whereby the jets IOO of flame from the openings O are caused to strike directly against the bottom before escaping upward or outward. The jets must strike the generator-chamber A before they can escape. Waste heat is thereby avoided and vapor is more readily produced.

Having thus described my invention, I claiml. The combination, in a vapor-burner, of the generatingchamber A, surrounding the vertical space or opening B, and the combined mixing-chamber and burner-head arranged under the generating-chamber, the said mixing-chamber and burner-head having the oileup P formed in the top of its cap, substan tially as described.

2. The burner-head having its cap formed with a depressed top,\vhich provides a receptacle for oil to start the generation of vapor, in combination with the generating-chamber arranged over the burner-head, substantially as described.

3. The generating-chamber A., surrounding the space or opening B, which is open from top to bottom throughout, combined with the burner-head M, arranged vertically below the generator and separate and distinct from the same, the bottom of the generator-chamber and the top of the burnerhead being separated from each other by an intervening space, 3o so that the free draft of air is allowed up the opening B to assist combustion, said burnerhead having openings O in the top, which openings are adapted to direct jets of alne against the bottoni of the generator-chamber. 3 5

4. In combination with the generatingchamber A, the burner having its cap or top provided with the depressed portion forming the oil-cup, and the series of openings O in the cap outside the oil-cup, said openings() being 4o arranged directly below the bottom of the chamber A, as set forth.

5. In a vapor-burner, the generatingchamber A,surrounding a central air space or opening, combined with the burner arranged below 45 and out of contact with the under side of the generating-chamber, so that the burner will not close the central opening or space, but the latter will be entirely open at the top and bottom for the passage of air upward, as and for 5o the purpose set forth.

In testimony that Ielaim the foregoing as my own I have hereto affixed my signature inpresence of two witnesses.
